Diagnosis

One of only four species of Phanerotoma that have an indented carapace. It differs from the other species by the ratio of metasoma to mesosoma being less or equal to 1 ( P. bonboniensis : more than 1), ratio of length to width of antennomeres being less than 3.5 (P. fi licornis more than 4), and its dark colour ( P. australiensis is yellow brown with black teeth).
